Coronary Artery Disease Phenotype Detection in an Academic Hospital System Setting.

BACKGROUND: The United States, and especially West Virginia, have a tremendous burden of coronary artery disease (CAD). Undiagnosed familial hypercholesterolemia (FH) is an important factor for CAD in the U.S. Identification of a CAD phenotype is an initial step to find families with FH. OBJECTIVE: We hypothesized that a CAD phenotype detection algorithm that uses discrete data elements from electronic health records (EHRs) can be validated from EHR information housed in a data repository. METHODS: We developed an algorithm to detect a CAD phenotype which searched through discrete data elements, such as diagnosis, problem lists, medical history, billing, and procedure (International Classification of Diseases [ICD]-9/10 and Current Procedural Terminology [CPT]) codes. The algorithm was applied to two cohorts of 500 patients, each with varying characteristics. The second (younger) cohort consisted of parents from a school child screening program. We then determined which patients had CAD by systematic, blinded review of EHRs. Following this, we revised the algorithm by refining the acceptable diagnoses and procedures. We ran the second algorithm on the same cohorts and determined the accuracy of the modification. RESULTS: CAD phenotype Algorithm I was 89.6% accurate, 94.6% sensitive, and 85.6% specific for group 1. After revising the algorithm (denoted CAD Algorithm II) and applying it to the same groups 1 and 2, sensitivity 98.2%, specificity 87.8%, and accuracy 92.4; accuracy 93% for group 2. Group 1 F1 score was 92.4%. Specific ICD-10 and CPT codes such as "coronary angiography through a vein graft" were more useful than generic terms. CONCLUSION: We have created an algorithm, CAD Algorithm II, that detects CAD on a large scale with high accuracy and sensitivity (recall). It has proven useful among varied patient populations. Use of this algorithm can extend to monitor a registry of patients in an EHR and/or to identify a group such as those with likely FH.

Advancing Social Work Education for Health Impact.

Social work education plays a critical role in preparing social workers to lead efforts that improve health. Because of the dynamic health care landscape, schools of social work must educate students to facilitate health care system improvements, enhance population health, and reduce medical costs. We reviewed the existing contributions of social work education and provided recommendations for improving the education of social workers in 6 key areas: aging, behavioral health, community health, global health, health reform, and health policy. We argue for systemic improvement in the curriculum at every level of education, including substantive increases in content in health, health care, health care ethics, and evaluating practice outcomes in health settings. Schools of social work can further increase the impact of the profession by enhancing the curricular focus on broad content areas such as prevention, health equity, population and community health, and health advocacy.

Structural and organizational characteristics associated with performance of essential public health services in small jurisdictions: findings from a statewide study in Massachusetts.

BACKGROUND: This study examined jurisdictional, organizational, and structural characteristics associated with capacity to deliver 10 essential public health services (EPHS) in Massachusetts, a state where a majority of local public health departments serve small municipalities. DESIGN: A survey was administered to local health directors or board of health chairs. MEASURES: The main outcome of the study was capacity to perform EPHS, measured by a 25-item screening tool. RESULTS: Seventy percent of the 351 boards of health in Massachusetts participated in the study. Greatest capacity was demonstrated in EPHS 2 (Diagnose and Investigate Health Problems) and EPHS 6 (Enforce Laws and Regulations). The capacity to perform the 8 other essential services was limited. Bivariate analysis indicates that overall capacity to perform EPHS is significantly associated with population size, poverty rate, annual municipal budget, and perceived understanding of the roles and responsibilities of local boards of health among elected municipal officials. The latter was the strongest predictor of overall capacity in multivariate analysis. CONCLUSIONS: Findings are aligned with studies examining factors associated with capacity to perform EPHS in large public health jurisdictions. The results suggest that one strategy for improving capacity to perform EPHS in smaller jurisdictions is to educate elected municipal leaders about the responsibilities of local health officials. Clarification regarding the role small jurisdictions with limited resources can play to ensure the equitable delivery of essential public health services and a strategy for measuring their contributions is important, especially as the national public health accreditation program gains momentum in the United States.

Development of a homology model for clade A human immunodeficiency virus type 1 gp120 to localize temporal substitutions arising in recently infected women.

The virus population transmitted by a human immunodeficiency virus type 1 (HIV-1) infected individual undergoes restriction and subsequent diversification in the new host. However, in contrast to men, who have limited virus diversity at seroconversion, there is measurable diversity in viral envelope gene sequences in women infected with clade A HIV-1. In this study, virus sequence diversity in three unrelated, clade A infected women preceding and shortly after seroconversion was evaluated. It was demonstrated that there is measurable evolution of envelope gene sequences over this time interval. Furthermore, in each of the three individuals, amino acid substitutions arose at five or six positions in sequences derived at or shortly after seroconversion relative to sequences obtained from the seronegative sample. Presented here is a model of clade A gp120 to determine the location of substitutions that appeared as the virus population became established in three clade A HIV-1 infected women.
